An Approach To Optimal Hyperspectral And Multispectral Signature And Image Fusion For Detecting Hidden Targets On Shorelines, Charles R. Bostater
An Approach To Optimal Hyperspectral And Multispectral Signature And Image Fusion For Detecting Hidden Targets On Shorelines, Charles R. Bostater
Ocean Engineering and Marine Sciences Faculty Publications
Hyperspectral and multispectral imagery of shorelines collected from airborne and shipborne platforms are used following pushbroom imagery corrections using inertial motion motions units and augmented global positioning data and Kalman filtering. Corrected radiance or reflectance images are then used to optimize synthetic high spatial resolution spectral signatures resulting from an optimized data fusion process. The process demonstrated utilizes littoral zone features from imagery acquired in the Gulf of Mexico region. Shoreline imagery along the Banana River, Florida, is presented that utilizes a technique that makes use of numerically embedded targets in both higher spatial resolution multispectral images and lower spatial …

Shallow Water Surface Gravity Wave Imaging, Spectra And Their Use In Shallow Water Dredging Operations, Charles R. Bostater, Bingyu Yang
Ocean Engineering and Marine Sciences Faculty Publications
Imaging of shallow waters using high resolution video imagery is described. Common to mono, stereo and trinocular imaging approaches from ground and airborne platforms is the need to validate the surface water wave field measurements, particularly the amplitude and specular reflectance of water surface small gravity waves. A technique for calibration and validation of water surface gravity wave field energy spectra is described. Results demonstrate the value of video imagery where water level staff gauges with approximately with 0.5 cm wave height accuracy are easily sensed using high definition videography. Essentially, a staff gauge placed in shallow water constructed from …

Operational Multi-Angle Hyperspectral Sensing For Feature Detection, Charles R. Bostater, Donald K. Brooks
Ocean Engineering and Marine Sciences Faculty Publications
Remote sensing results of land and water surfaces from airborne and satellite platforms are dependent upon the illumination geometry and the sensor viewing geometry. Correction of pushbroom hyperspectral imagery can be achieved using bidirectional reflectance factors (BRF's) image features based upon their multi-angle hyperspectral signatures. Ground validation of features and targets utilize non-imaging sensors such as hemispherical goniometers. In this paper, a new linear translation based hyperspectral imaging goniometer system is described. Imagery and hyperspectral signatures obtained from a rotation stage platform and the new linear non-hemispherical goniometer system shows applications and a multi-angle correction approach for multi-angle hyperspectral pushbroom …
Acquisition Of Airborne Imagery In Support Of Deepwater Horizon Oil Spill Recovery Assessments, Charles R. Bostater, Frank Edgar Müller-Karger
Acquisition Of Airborne Imagery In Support Of Deepwater Horizon Oil Spill Recovery Assessments, Charles R. Bostater, Frank Edgar Müller-Karger
Ocean Engineering and Marine Sciences Faculty Publications
Remote sensing imagery was collected from a low flying aircraft along the near coastal waters of the Florida Panhandle and northern Gulf of Mexico and into Barataria Bay, Louisiana, USA, during March 2011. Imagery was acquired from an aircraft that simultaneously collected traditional photogrammetric film imagery, digital video, digital still images, and digital hyperspectral imagery. The original purpose of the project was to collect airborne imagery to support assessment of weathered oil in littoral areas influenced by the Deepwater Horizon oil and gas spill that occurred during the spring and summer of 2010. This paper describes the data acquired and …

Remote Sensing Of Shorelines Using Data Fusion Of Hyperspectral And Multispectral Imagery Acquired From Mobile And Fixed Platforms, Charles R. Bostater, Heather Frystacky
Ocean Engineering and Marine Sciences Faculty Publications
An optimized data fusion methodology is presented and makes use of airborne and vessel mounted hyperspectral and multispectral imagery acquired at littoral zones in Florida and the northern Gulf of Mexico. The results demonstrate the use of hyperspectral-multispectral data fusion anomaly detection along shorelines and in surface and subsurface waters. Hyperspectral imagery utilized in the data fusion analysis was collected using a 64-1024 channel, 1376 pixel swath width; temperature stabilized sensing system; an integrated inertial motion unit; and differential GPS. The imaging system is calibrated using dual 18 inch calibration spheres, spectral line sources, and custom line targets. Simultaneously collected …

Collection of pushbroom sensor imagery from a mobile platform requires corrections using inertial measurement units (IMU's) and DGPS in order to create useable imagery for environmental monitoring and surveillance of shorelines in freshwater systems, coastal littoral zones and harbor areas. This paper describes a suite of imaging systems used during collection of hyperspectral imagery in northern Florida panhandle and Gulf of Mexico airborne missions to detect weathered oil in coastal littoral zones. Underlying concepts of pushbroom imagery, the needed corrections for directional changes using DGPS and corrections for platform yaw, pitch, and roll using IMU data is described as well …

Modeling The Influence Of Water Waves Upon Remote Sensing Imagery: The Underwater Radiance Distribution And Shape Factors, Charles R. Bostater, Luce Bassetti, Lisa H. Huddleston
Ocean Engineering and Marine Sciences Faculty Publications
This paper describes the results of modeling the water wave surface and underwater light field as influenced by water waves using a Monte Carlo model (MCHSIM). Model and sensor data related to water column properties and benthic properties that influence the light upwelled from below the water - as observed from a sensor looking from below or above the water surface is presented. Synthetic image results using Monte Carlo techniques show the influence of water waves upon subsurface shape factors and these factors can be used in shallow water remote sensing algorithms that are based on underlying analytical models. The …

Simulated and airborne imagery demonstrate the ability to see manmade and natural objects below the water wave surface. Traditional photogrammetric imagery and airborne digital imagery both suffer from a loss in image clarity due to a number of factors, including the forward motion of the airborne platform. Blurring due to this effect can be calculated and an opto-mechanical system has been designed in order to help remove this effect. Forward motion blur can be shown to occur on the order of a several centimeters and calculation results are presented. The system is described and imagery is shown to demonstrate image …
